Schlumbergera plant named ‘Sao Paulo Brazil’

ABSTRACT

A new and distinct cultivar of  Schlumbergera  plant named ‘Sao Paulo Brazil’, characterized by its pure white colored flowers; dense and bushy plant form; and moderate growth habit.

Latin name of the genus and species claimed: Schlumbergera truncata hybr.

Variety denomination: ‘SAO PAULO BRAZIL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Schlumbergera plant, botanically known as Schlumbergera truncata hybr., common name Thanksgiving Cactus, and hereinafter referred to by the variety denomination ‘Sao Paulo Brazil’.

The new Schlumbergera is a product of a planned breeding program conducted by the inventor, Frank Rohde, in Fyn, Denmark. The new Schlumbergera originated from an outcrossing made in 2007 by the Inventor between two proprietary cultivars of Schlumbergera truncata hybr. The female or seed parent is the Schlumbergera truncata hybr. variety designated ‘Jolly Dancer’ (unpatented). The male or pollen parent is the proprietary Schlumbergera truncata hybr. variety designated 3666 C (unpatented). The Inventor selected the new Schlumbergera cultivar from the progeny of the above crossing in 2008 on the basis of its flower color and fairly compact, freely branching habit. Plants of the new Schlumbergera are more upright, and have a unique color combination of the flowers combined with healthy, shiny dark green phyllocladia and excellent branching.

Asexual reproduction of the new cultivar by phyllocladia cuttings taken and propagated and trial production batches in Fyn, Denmark, has shown that the unique features of this new Schlumbergera are stable and reproduced true to type in many successive generations.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sao Paulo’. These characteristics in combination distinguish ‘Sao Paulo’ as a new and distinct cultivar:

-   -   1. Pure white flowers;     -   2. Large upright to vertical flowers with less reflexing of         petals;     -   3. Moderately vigorous growth habit;     -   4. Higher number of flowers per plant;     -   5. White buds, ovoid to lanceolatoid in shape.

Plants of the cultivar ‘Sao Paulo’ can be compared to plants of the Schlumbergera truncata hybr. cultivar ‘Malissa’ (unpatented). However, in side-by-side comparisons conducted over several seasons by the inventor in Hundslev, Denmark, plants of the cultivar ‘Sao Paulo Brazil’ and the cultivar ‘Malissa’ differ in the following characteristics:

-   -   1. Plants of the new Schlumbergera have larger flowers than         plants of the cultivar ‘Malissa’.     -   2. Plants of the new Schlumbergera have less reflexing petals         than plants of the cultivar ‘Malissa’.     -   3. Plants of the new Schlumbergera have longer and darker green         (RHS 137A) phyllocladia than plants of the cultivar ‘Malissa’         (RHS 137B).     -   4. Plants of the new Schlumbergera have more serrated         phyllocladia compared to ‘Malissa’.     -   5. Plants of the new Schlumbergera are taller than the plants of         the cultivar ‘Malissa’     -   6. Plants of the new Schlumbergera have more flowers per plant         than the plants of the cultivar ‘Malissa’

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and details of flower form color and structures of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which more accurately describe the actual colors of the claimed variety.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar ‘Sao Paulo Brazil’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 4^(th) edition, where general terms of ordinary dictionary significance are used. Plants were grown under greenhouse conditions. Plants used for this description were grown for about 40 weeks after cutting.
